Answer:

Let, the age of AI be 'x' years, the age of Barb be 'y' years and the age of Cindy be 'z' years.

Let, the age of AI be 'x' years, the age of Barb be 'y' years and the age of Cindy be 'z' years. Then,

Let, the age of AI be 'x' years, the age of Barb be 'y' years and the age of Cindy be 'z' years. Then,According to question,

x= y + 7 ............(i)

z= 3y.................(ii)

ii)

Now,

x + y + z= 62 ( From question)

Replacing the value of x ans z from equation (i) and (ii)

or, y + 7 + y + 3y = 62

or, 5y + 7 = 62

or, 5y = 55

. ° . y = 11 years

Again,

Again, In equation(i)

x = y + 7

or, x = 11 + 7

. ° . x= 18 years.

Hence, the age of AI is 18 years.
